Summary
Most smoke detectors use a small pellet of americium-241 (atomic number 95), used to ionize the air to detect smoke particles.
Americium-241 is a synthetic, radioactive heavy isotope with a half-life of 432.2 years. It decays via alpha emission and spontaneous fission. This means that, after 25 years, about 4% of the original americium in your smoke detector has transmuted into neptunium-237 and other lighter elements.By topquark22
